Hey, Shiv! I don't know if you'd call it dancing, but I love Pilobolus (WS). On a completely unrelated note, Late Bloomer, a short film with a Lovecraftian take on sex ed, is brilliant (but don't watch it at work).

I'm sad because soon I'll have to go home (to a place without decent 'net access). Woe. *spams while she can*

P.S. Here's another vid (WS): The Worst Couple in the World (Star Wars style). If anyone knows what the voice-over is from, would you please let me know?
